Application December 13, 1943, Serial No. 514,086

1 Claim. 1

My invention relates to improvements in. tools and, more specifically,to an improvement in watchmakers tools, and while applicable to variousinstruments, such, for instance, as chronographs and the like, yet Ihave designed it more particularly for use in connection with watcheshaving a sweep second wheel or any similar wheels held or carried onpinions by friction, the use of like tools being well understood bythose skilled in the art.

If a sweep wheel is removed by ordinary watchmakers tools the rim of thewheel is frequently bent and thus the substitution of a new sweep wheelis necessary. Moreover, the watch plate is usually marred, which is alsohighly objec tionable.

It is, therefore, the main object of the present invention to facilitatethe removal of sweep wheels or the like from the third wheel pinionwithout the danger of breaking or bending said pinion or the rim of thesweep Wheel and without damaging other parts of the watch; anotherobject of the invention is to provide a tool of this character whichshall be simple in construction, of but few parts easily and readilyassembled, and therefore economical to manufacture, and which shall beeffective for the purposes for which the same is intended.

Further objects of the instant invention reside in any novel feature ofconstruction or operation or novel combination of parts present in theembodiment of the invention described and shown in the accompanyingdrawing whether within or without the scope of the appended claim andirrespective of other specific statements as to the scope of theinvention contained herein.

In the drawing:

Figure 1 is a plan view of a preferred embodiment of my invention;

Figure 2 is a side elevation of the same;

Figure 3 is a front elevation of the same;

Figure 4 is another side elevation showing the device when holding asweep wheel and being 4 drawn in an enlarged scale; and

Figure 5 is a front elevation of the device holding a sweep wheel andbeing also drawn in an enlarged scale.

Similar numerals refer to similar parts throughout the several views.

Referring to the drawing, it will be seen that the device consists oftwo flat tweezers legs or spring jaw members 3 and 4 and of a body orcentral part I, which is formed by the joined upper ends of the members3 and 4. Whereas the upper ends of the members 3 and 4 can be fastenedtogether by means of a pivot (not shown) similar as the legs of a pairof compasses, or by riveting, or the like, I prefer to fasten them toingtheir points into convenient shape for handling small and delicateobjects.

The lower end of the tweezers leg or spring jaw member 3 is reduced insize and provides a shoulder 3a at the juncture of the reduced portionwith the wider and thicker upper portion,

this shoulder serving as a limit stop to abut against the sweep wheel.The reduced end portion is formed as an inwardly bent, pointed claw I 5adapted to be inserted under the center portion of a sweep wheel 1 orthe like so that claw 5 engages the wheel between two spokes; whereasthe lower end of member 4 is likewise reduced in size to provide ashoulder 411 at the juncture of the reduced portion with the wider andthicker portion to cooperate with the shoulder 3a.. The reduced endportion is formed as an inwardly bent fork 6 having pointed prongsadapted to be also inserted under the center portion" of a. wheel 1 insuch a manner that a spoke of said wheel is located between said prongs.This Way of engaging the center portion of a wheel I, as illustrated inFigures 4 and 5, allows a safe manipulation of the wheel and. makes itunnecessary to engage or even to touch the rim of wheel 'I.'

As soon as the parts 5 and 6 have (clasped the center portion of wheel 1between the spokes in the manner previously referred to, the wheel 1 canbe removed from the watch by applying pressure on the members 3 and 4 sothat the wedgeshaped prongs will force the sweep wheel upwards off thepinion.

While there has been shown and described and pointed out the fundamentalnovel features of the invention as applied to a single modification, itwill be understood that various omissions and substitutions and changesin the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing from thespirit of the invention.

3 7 It is the intention, therefore, to be limited only as indicated bythe scope of the following claim. I

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is:

A tool consisting of the combination, in one implement, of tweezershaving two spring jaw members which are fastened together at their upperends and the lower end of one spring jaw member having a, reducedportion forming an inwardly bent pointed serted under the center clawadapted to be in-] portion of a wheel be-' "tween two spokes whereas thelower end of the r other spring jaw member has a'reduced portion v andforms an inwardly bent fork having pointed prongs adapted to be insertedunder the center portion of a wheel in such a manner that a spoke ofsaid wheel is situated between said prongs,

and a central part consisting of the joined upper ends of said springjaw members, a shoulder being provided at the inner side of each of saidspring jaw members, one of said shoulders being located at the juncturebetween the pointed claw and its adjoining enlarged spring jaw memberportion, and the other at the bottom of the slots between the claws ofstantially asset forth.
